The study was carried out to evaluate the anti-ulcerative and gastroprotective effect of DLBS2411, a bioactive fraction from (Nees & T. Nees) Blume, in Wistar rats ().
The rats were divided into five treatment groups, which were the Normal control group, Negative control group (ethanol-induced) and two treatment groups: DLBS2411 at the doses of 25 mg/kg body weight (BW) and 50 mg/kg BW, and the Positive control group treated with sucralfate at the dose of 100 mg/kg BW. Gastroprotective effect was measured by the ulcerative lesion index, ulcer surface area, percentage of lesion area, and cure ratio. Hematological and histopathological analyses were also conducted to gain additional data regarding the gastroprotective effect of DLBS2411 in the rats' stomachs.
DLBS2411 was found to contain not less than 15% of total phenolic compounds. Treatment with DLBS2411 at doses of 25 mg/kg BW and 50 mg/kg BW significantly reduced the percentage of ulcer area in rats. The percentage of ulcer area for the Negative control group and both doses in the DLBS2411 treatment group reached 22.64±6.82%, 6.75±4.41%, and 6.18±4.63%, respectively. Ulcer surface area in the treatment groups and Positive control group also decreased. Histopathological data showed that gastric epithelial cells in the Negative control group were more severely ulcerated than in the treatment group of DLBS2411 and the Positive control group.
This study showed that DLBS2411 at the dose of 50 mg/kg BW was more effective in protecting the stomach lining than DLBS2411 at the dose of 25 mg/kg BW, as measured by percentage of ulceration inhibition and the ulcerative lesion index.
本研究旨在评估来自(Nees & T. Nees)Blume的生物活性成分DLBS2411对Wistar大鼠()的抗溃疡和胃保护作用。
将大鼠分为五个治疗组,即正常对照组、阴性对照组(乙醇诱导)和两个治疗组:体重25mg/kg和50mg/kg的DLBS2411治疗组,以及阳性对照组(100mg/kg体重的硫糖铝治疗组)。通过溃疡病变指数、溃疡表面积、病变面积百分比和治愈率来测定胃保护作用。还进行了血液学和组织病理学分析,以获取关于DLBS2411对大鼠胃的胃保护作用的更多数据。
发现DLBS2411中总酚类化合物含量不少于15%。体重25mg/kg和50mg/kg的DLBS2411治疗组显著降低了大鼠溃疡面积的百分比。阴性对照组和DLBS2411治疗组两个剂量的溃疡面积百分比分别达到22.64±6.82%、6.75±4.41%和6.18±4.63%。治疗组和阳性对照组的溃疡表面积也有所减少。组织病理学数据显示,阴性对照组的胃上皮细胞溃疡比DLBS2411治疗组和阳性对照组更严重。
本研究表明,以溃疡抑制百分比和溃疡病变指数衡量,体重50mg/kg的DLBS2411比体重25mg/kg的DLBS2411在保护胃黏膜方面更有效。
